| 摘 要： | 在实验室环境研究轴流式通风机噪声的主动控制问题。轴流通风机的噪声主要由风叶旋转时的通频及其低次谐频成分构成 ,应用主动噪声控制技术能够有效地抑制这些离散频率上的声音。通过对多通道自适应控制系统的组成和算法的分析 ,设计了具有 4个误差输入和 2个抵消输出的ANC系统并应用于通风机噪声控制 ,获得了满意的实验结果。

| Abstract: | The initiative control of the noise producing by axial flow ventilator is investigated in experiment environment.The axial flow ventilator′s noise is mainly composed of general frequency and.harmonious frequency.Dispersed frequency can be controled effectively by using the initiative control technology.ANC system is designed to control the axial flow ventilator′s noise by analysing the component and algorithm of multi channel self adapting control system,and the results are satisfactory. |

| Keywords: | noise of axial flow ventilator initiative control and self adapting algorithm |
